NAEP Technical DocumentationRange of response codes, percent agreement, and Cohen's Kappa or intraclass correlation for the constructed-response items from previous years rescored in 2006, grade 4 civics assessment, by item and block: 2006
Block Item Range of response codes Sample size Percent of exact agreement Cohen’s Kappa Intraclass correlation
† The intraclass correlation is not reported for dichotomously scored items; Cohen's Kappa is not reported for polytomously scored items.
NOTE: Cohen's Kappa is a measure of reliability that is appropriate for items that are dichotomously scored. The intraclass correlation coefficient is most appropriate for items with more than two categories.
